Can IAC motor cause problems?

Hi. On idle warmed up IAC is about 2%. Drove a bit and at 1700 RPM the IAC shows suddenly 68%. Restart, but now the idle I barely working and IAC shows around 64%. Now AFR shows 35 the cars stalls. The Innovate Lambda sensor shows 9.5-10.1 AFR is in nearly the same position. With an external gauge. So it's basically overfueling. Let it cool down, but the same, 35 AFR and IAC 68%. Went into advanced tuning IAC and played around with the graph. The IAC moves the piston back and forth. Pulled the IAC away from the Sniper unit. And the tip nearly fell out. Can all this malfunction be caused by a bad IAC? Regards, Rob

Hi. Thanks Danny. The WBO2 sensor was brand new, so it got destroyed in five minutes of driving. Anyway to check for faulty ECU? But the Innovate WBO2 sensor is still working. TPS sensor is also new, so is the CTS sensor. Regards, Rob
